Answer:
Usually in the equation they use Sin, Cos, or tan. Although, If the point in the graph starts at 0 is is sin and anything else would be cos. Tan is the sort of vertical squiggly line.
Step-by-step explanation:
Answer:
n = -1
Step-by-step explanation:
The period of cos is 2π
so the period of cos(4x + π) is 2π/4 = π/2
cos(4x + π) = -cos4x => <span>-3 cos(4x + π) + 6 = 3cos4x + 6
phase shift may be [-</span>π/4,π/4]
amplitude is [-3,3]
